The Timex Social Club was a U.S. group formed in 1982 by students of Berkeley High School in Berkeley, California. Originally known as The Timex Crew, members included Marcus Thompson (founder), Gregory "Greg B" Thomas, Michael Marshall, Craig Samuel and Darrien Cleage. By 1985, Samuel, Cleage and Thomas had departed, and both Alex Hill and Kevin Moore were added to complete the group, and the name Timex Social Club was adopted. They specialized in both old school hip hop and the merger of urban R&B with hip hop rhythms, which were later known as new jack swing.
